论文摘要
实验室（激光和Z-PINCH）的不透明度测量表征良好的等离子体提供了数据以帮助惯性限制融合，天体物理学和原子物理学研究。为了测试用于计算热等离子体的辐射特性的原子物理代码，此类实验必须满足许多要求。在这项工作中，我们讨论了吸收 - 光谱实验中的一些不确定性来源，有关面质量，背景发射，反射仪的强度和血浆的自我发射。我们还研究了样品的空间不均匀性的影响。
Laboratory (laser and Z-pinch) opacity measurements of well-characterized plasmas provide data to assist inertial confinement fusion, astrophysics and atomic-physics research. In order to test the atomic-physics codes devoted to the calculation of radiative properties of hot plasmas, such experiments must fulfill a number of requirements. In this work, we discuss some sources of uncertainty in absorption-spectroscopy experiments, concerning areal mass, background emission, intensity of the backlighter and self-emission of the plasma. We also study the impact of spatial non-uniformities of the sample.
